COVID-19 infections were high among hospital staff but re-infection rates are very low
A study of healthcare workers shows they were three times more likely to become infected during the COVID-19 pandemic compared to the general population. However, health care workers who had been infected were very unlikely to contract COVID-19 a second time in the following six months.

RMRS scientists recommend approach to adapt to uncertainty in wildland management
Scientists from the Rocky Mountain Research Station collaborated to explore how research and management can confront increasing uncertainty due to climate change, invasive species, and land use conversion. In new research published in Frontiers in Forests and Global Change, the authors recommend a more inclusive and collaborative governance model that would increase public and stakeholder participation, integrate research and management, and incorporate multiple forms of knowledge, including from indigenous communities.

Columbia Engineering team builds first hacker-resistant cloud software system
Columbia Engineering researchers have developed SeKVM, the first system that guarantees--through a mathematical proof--the security of virtual machines in the cloud. "This is the first time that a real-world multiprocessor software system has been shown to be mathematically correct and secure," said Computer Science Professor Jason Nieh. "This means that users' data are correctly managed by software running in the cloud and are safe from security bugs and hackers."

New study shines light on hazards of Earth's largest volcano
Scientists from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science analyzed ground movements measured by Interferometric Synthetic Aperture Radar (InSAR) satellite data and GPS stations to precisely model where magma intruded and how magma influx changed over time, as well as where faults under the flanks moved without generating significant earthquakes.

Chemical changes to peptide siRNA-carrier enhance gene silencing for future cancer drugs
Hollings researchers found a modified peptide carrier that was delivering the siRNA drug by adhering to and potentially moving along cell filopodia, leading to more efficient cell entry and improved gene silencing.

Evacuating under dire wildfire scenarios
As climate change intensifies, wildfires in the West are behaving in ways that were unimaginable in the past--and the common disaster response approaches are woefully unprepared for this new reality. In a recent study, a team of researchers led by the University of Utah proposed a framework for simulating dire scenarios, which the authors define as scenarios where there is less time to evacuate an area than is required.

Lundquist investigator Wei Yan solves longstanding fallopian tube transport debate
Yan research group has solved a longstanding scientific debate about the mechanism underlying the gamete and embryo transport within the Fallopian tube. Using a mouse model where the animals lacked motile cilia in the oviduct, they demonstrated that motile cilia in the very distal end of the Fallopian tube, the infundibulum, are essential for oocyte pickup. The finding was published in the Proceedings of the National Academy of Sciences (PNAS).

Enzymes of a feather: CRISPR-Cas components work together to enhance protection from viruses
Researchers from Skoltech and their colleagues from Russia and the US have shown that the two components of the bacterial CRISPR-Cas immunity system, one that destroys foreign genetic elements such as viruses and another that creates "memories" of foreign genetic elements by storing fragments of their DNA in a special location of bacterial genome, are physically linked. This link helps bacteria to efficiently update their immune memory when infected by mutant viruses that learned to evade the CRISPR-Cas defense.

COVID-19 infection rates of dentists remain lower than other health professionals
More than a year after COVID-19 appeared in the U.S., dentists continue to have a lower infection rate than other front-line health professionals, such as nurses and physicians, according to a study published online ahead of the June print issue in The Journal of the American Dental Association. The study, "COVID19 among Dentists in the U.S. and Associated Infection Control: a six-month longitudinal study," is based on data collected June 9 - Nov. 13, 2020.
